MOTIVE POWER FOR JIGGING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 432,892, dated July 22, 1890. Application filed May l, 1890. Serial No. 350,218. (No model.)

To all whom t may concern:

Be it known that I, JAMES NICHOLAS, of Benton, in the county of Lafayette and State of Wisconsin, have invented anew and useful Improvement in Motive Power for .ligging- Machines, of which the following isa specification.

.My invention consists in a new and improved niotive power, which is especially intended for driving jiggingmachines, but which may be employed for a variety of other purposes, and my invention will be hereinafter fully described and claimed.

Referring `to the accompanying drawings, Figure 1 is a side view of my improved machine. Fig. 2 is a top plan view of the same. Fig. 8 is a detail side view of the fly-wheel. Fig. 4 is a detail view of the pitmau-bolt, and Fig. 5 is a detail View of the pitman.

The same numerals of reference indicate corresponding parts in all the figures.

Referring to the several parts by their designating-numerals, 1 indicates the rectangular supporting-frame of my machine, this frame being preferably of oak, and having legs 2, on which it is supported. At about the middle of this frame 1 is mounted in bearings a transverse shaft 3, upon the central part of which is secured a large bevel cog-wheel 4, and the shaft 3, which may be called the drive-shaft, has a crank-handle 5 at one end, by means of which the drive-shaft and the wheel 4 are revolved.

6 6 indicate two shafts, which are mounted longitudinally on the frame 1 in bearings 7. On the inner end of each of these shafts is secured a bevel-pinion 8, which meshes with the drive-wheel 4, while upon the outer end of each shaft 6 is secured a large balance or iiy wheel 10, having one wide spoke with holes for pitmen. The bevel-pinions 8 are of such size that they will make about four revolutions for one revolution of the cog-wheel 4, with which they mesh. 'lhe iiy-wheels 10, at the outer ends of the shaft 6, are of such size and weight as are required for the work to be done, but are each formed with one wide spoke 11, formed with a series of adjusting holes or apertures 12, extending out from the hub of the wheel toward its periphery, in any one of which the pitman-bolt 13 may be placed.

The body of this pivot-bolt, whichis-shown in detail in Fig'. 4, is formed at one end with a flange or head 13a, while its other endis reduced to form a pivot-pin 14 and threaded at its end for a nut 15.

16 indicates the pitman, which is formed at its lower end with a circular opening 17, and it will be seen that when the pivot-bolt is placed through any one of the apertures 12 of the ily-wheel and the apertured end of the pitman placed on the pivot pin the flanged end of the bolt will hold it in place in the apertured spoke, while the nut 15 will hold the bolt at that end. The pitman has at its upper end a curved eye 18, by means of which the upper end of the pitman is connected or secured to the outer end of the tongue 19 of a jigging-machine by pressing it through the eye, as shown in Fig. 3, or to a sieve, a wood-saw, a churn-crank, a grindstone-handle, a pump, &c., my invention being applicable to many different purposes or machines, besides its principal purpose of driving jiggingmachines, as will be readily understood.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my new and improved motive power will be readily seen. The upper ends of the pitmen 16 of the two balanoe-wheels being secured to the outer ends of the tongues of one or more jigging-machines, as shown in Fig. 1, the large drive cog-wheel 4 is revolved by turning the crank-handle 5, and this cogwheel 4, meshing with the small pinions 8 on the inner ends of the longitudinal shafts 6, rapidly revolves the said shafts and the large balance-wheels at their outer ends, which, through the connecting-pitmen 16, rapidly oscillate and work up and down the tongues of the jigging-machine.

By my invention the old laborious working up and down of the jig-tongue 19 by the hand is done away with, and the easy rotary motion of the crank-handle 5 substituted therefor, while three times the amount of Work is accomplished. The large balance-wheels 10 operate to cause the machine to run easily and smoothly, while by forming the broad IOO spoke of the balance-wheels with. the series of bolt-apertures 12 the end of the pitman can be moved nearer to or farther from the hub or center of the said Wheels, thus increasing or decreasing the length and power of the strokes of the jig-tongues, enabling the operator to regulate the movements or stroke ac' cording to the nature of the Work to be done.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

l. The combination of the transverse shaft having the crank-handle, and the beveled cog- Wheel mounted on said shaft, the shafts 6,

having the bevel cog-pinions at their inner ends and the balance-Wheels. at their outer ends, and pitrnen pivotally connecting the said balance-Wheels with the outer ends of the jigging-Vmachine tongues, substantially as set fort-l1.

2. The combination of the transverse shaft having the crank-handle and the beveled cog- Wheel mounted on said shaft, the shafts 6, having at their inner ends the bevel-pinions, the balance-Wheels, formed each with a Wide spoke having the series of bolt-apertures l2, the removable pitman-bolts 13, and the pitmen formed with the aperture at their lower 4ends andhaving at their upper ends the curved eye 18, substantially as set forth.
